Heuristic model of Purcell enhancement in photonic crystal waveguides

We present a heuristic mathematical model of the relation between the geometry of a photonic crystal waveguide and the Purcell-enhancement factor at a particular wavelength of interest. We use this model to propose approaches to the design of a photonic crystal waveguide maximizing the Purcell enhancement at a target wavelength. Numerical simulations indicate that the proposed model allows controlled variation of Purcell-factor peak width and height, which can be used to achieve increased robustness with regard to fabrication defects.
